a766 unlock prob. - GSM-Forum

chicodon · 08-30-2010, 00:34

hello, i need help unlocking samsung a766,

i cannot activate qualcomm mode when a sim card is inserted (i don't have the sim card to the network the phone is locked to).
when other sim card is inserted the phone just asks for net. unlock code.

when i use download mode to read "mobile info" or "unlock" i get this
PING: OK, COM35 - NOT IN MODEM MODE !

but if i should click on "mobile info" or "unlock" immediately after first error i get this:

PING: OK, COM35 - MODEM
QC_MOD_WRITE_ACK_ERR:

PING: OK, COM35 - MODEM
QC_MOD_WRITE_ACK_ERR:
PHONE Lock Reset Failed
QC_MOD_WRITE_ACK_ERR: 7F030100000000007D5E8F0C7E
SIM Lock Reset Failed

please help.
thanks

you can use rj45 e210 cable
and read codes using qcdi without qualcomm mode
only need uncheck qc mode box

Major-T · 08-30-2010, 00:51

to activate qualcomm mode not need sim card inserted
insert card after it is activated
switch off switch on not change phone mode

can read codes without sim card:
1. enter QC mode
2. connect cable
3. enter *#7465625#
will see simlock info on lcd, press ok
4. pres qcdi on software
